When I simulate the UR package in https://github.com/ros-industrial/uni... , I run the

roslaunch ur_gazebo ur5.launch

and

roslaunch ur5_moveit_config ur5_moveit_planning_execution.launch sim:=true

it turned out the error:

MoveItSimpleControllerManager: Action client not connected: /follow_joint_trajectory

Is I miss something? My system version is ubuntu14.04+indigo

roslaunch ur_gazebo ur5.launch
roslaunch ur5_moveit_config ur5_moveit_planning_execution.launch sim:=true
roslaunch ur5_moveit_config moveit_rviz.launch config:=true

I don't think this is correct. When simulating using Gazebo, the driver (any driver) isn't used.

but how to use motion planning, how do u move ur5??!!

Not with the driver.

ur_gazebo includes a setup for gazebo_ros_control (ie: ros_control in Gazebo), which exposes the same Action based interface as the driver. That is what you use to control the robot.

could you please tell me how do u move ur5 with only launching roslaunch ur_gazebo ur5.launch I understand that u still need driver !!!!

Have you seen the instructions in the readme of the universal_robot repository? Specifically the section Usage with Gazebo Simulation.

oh, ok, then ur_modern_driver is only used for real ur5, thx letting me know.
